    easy to use, easy to wire up, only downside is a very loud relay, was making a passive cooler using a peltier element

    Štefan, I finally decided to use it for temperature control of my power supply cooling.

    Première photo la température ambiante. Deuxième photo Appui court sur set pour entrer la température de consi!gne 23.2 . Troisième photo appuie long puis + pour sélectionner P1 qui est l hysteresis. Appui sur set pour entrer l hysteresis ici 0,5 (2 degrés la valeur par défaut) attendre 5seconde pour le retour à l affichage. Mettre son doigt sur la sonde pour monter en température a 23.7 (23,2 + 0,5 hysteresis) la led s allume et le relai colle. On retire le doigt de la sonde la température baisse. La led s éteindra à la température de consigne 23,2

    I bought 3 kits. Great thermostat at a small price. For usage documentation: www.kelco.rs/katalog/images/17670.pdf Test parameters: P0 = C (default), P1 = 0.8 ° C (hysteresis), limit temperature = 33 ° C. Photo 2: error - probe not connected. Photo 3: led ON - closed relay contact - temperature below set maximum limit. Photo 4: led OFF - open relay contact - lower temperature than set hysteresis limit.

    Order was shipped and arrived very fast in good packaging. This device does what it promises for a very good price. I tested it and found out that digital indication is at Celcious degrees and there is a small deviation of about 2 degrees that is not a big deal for the type and purpose of usage. Setting up is really easy using the 3 buttons. By pressing the left button (the one close to relay) you are enterring setup and digital segments are flashing ... In this status you can use the 2 other buttons to set up and down the value of desired triggering temperature ... Then by pressing the left button you store the value. JUST that simple !!! I surely recommend this product and i have already ordered more !

    The module runs on a 12V DC supply and draws about 20mA or 70mA when the relay is energised. Here's the programming info: A brief press of SET enters the main temperature adjustment mode with the current set temperature flashing. This can be adjusted with the UP/DN buttons, and holding them will make them auto-repeat. When finished adjusting, the unit will store your new setting and revert back to normal operation after several seconds. Holding down SET for about 5 seconds will enter programming mode. You can step through the program parameters from P0 to P6 with the UP/DN buttons and use SET to select them. P0 Selects cooling mode or heating mode.In cooling mode (C) the relay will energise and close the contacts when the probe temperature is above the set temperature.In heating mode (H) the relay will energise and close the contacts when the probe temperature is below the set temperature. P1 Allows you to set a hysteresis value between 0.1 to 15 degrees.The hysteresis value is to prevent the relay chattering ON and OFF when the probe is wavering around the set temperature point.For instance, with hysteresis set to the default of 2 degrees, when in cooling mode and the temperature is set to 25 degrees, the relay will activate as soon as that temperature is reached, but not deactivate until the temperature is brought down to 23 degrees (25 degrees minus a hysteresis value of 2 degrees)When in heating mode the relay would activate as soon as the temperature fell to 25 degrees, but would remain on until it reached 27 degrees. (25 degrees plus a hysteresis value of 2 degrees.) P2 Highest temperature limit. Set to 110 degrees by default. This is used to limit the upper temperature than can be set. P3 Lowest temperature limit. Set to -50 degrees by default. This sets the lowest temperature than can be set. P4 Probe correction. Very neat. Allows you to calibrate the temperature the probe is sensing by +7.0 to -7.0 in tenth of a degree increments. P5 Relay energisation delay of between 0 to 10 minutes to limit fast cycling of equipment like compressors. After setting this function the unit must be powered off and on again for the change to take effect. When I tested this it switched after about 35 seconds with a delay of "1" and about 1:40 with a delay of "2". P6. This is an over-temperature limit that turns off the relay and displays a row of dashes on the display.
